I want my sound volume to drop to zero after some time. I’ve tried to increase rolloff factor (distance factor is 1.0, as it should be) and it works (sound fades faster), but no matter how far I go from sound source, it is still there (although faint).

Is there an global options setting minimal sound volume? (I would say no)

How do I properly use FMOD_3D_LINEARROLLOFF? Do I have to set it before or after call to playSound() (using C++ interface)?

To my understanding, when using linear rolloff min distance is distance where linear attenuation starts, and max distance where it stops (i.e. volume is 0).
However, I wasn’t ablo to achieve this (sound doesn’t chage at all). It does change properly when using LOGROLLOFF (but does not go to zero, as mentioned before).

After setting min/max distance for channel, it somwhow works. It still does not go compleatelly silent (i.e. if I move 10000 units and max distance is set to 20 units, I can still hear it, its faint but can be heard). This is the only sound.
